Which variable is more suitable for analyzing surface air temperature? TS(Surface temperature (radiative)), T1000(Temperature at 1000 mbar pressure surface), TREFHT(Reference height temperature), or T(Temperature) ? |

The choice of variable depends on the purpose of your analysis. The most common one is Trefht i.e Temperature at reference height =2m so same as the measurements and commonly used in impact models. Ts= surface temperature so used for radiation calculations and measurements/retrievals and properties of the surface; Ts = Sea surface temperature over ocean. T is the temperature in the model layers, so 3D. The height above the surface varies with time and space and model. T1000: I have not looked at this one. I did a quick search and there are articles using it, e.g. DOI: 10.1175/2009JCLI2799.1 |

The purpose of that specific article was to compare how models estimate TREFHT from T after reducin…
